The Associated Press reports that a member of Jay-Z’s entourage maced R. Kelly during a joint concert at Madison Square Garden, Kelly’s publicist Allan Mayer said. The spraying happened about an hour into Friday night’s show, when Kelly walked on stage and said he saw two people in the audience waving guns, Mayer said. Kelly abruptly stopped his set at about 9:30 p.m. while Garden security employees searched for weapons.
